• Features:

 

High sensitivity probe, no radiation, low-ultrasound power, safety and with high accuracy.

Large LED display, you can see the fetal heart rate, battery capacity, and volumes clearly.

Equipped with volumes adjustable function, you can adjust the volumes easily according to your demands.

 

the external speaker of the device will be closed, without any sound output.

After hearing a recognizable, rhythmic fetal heart rate sound, keep the probe stationary for at least 5 seconds so that the device can measure and display the fetal heart rate correctly.

Powered by two sections of AA battery, support continuous operation. (battery is not included)

 

Note:

The normal fetal heart rate r-ange is 120-160bpm.

100-120bpm and 160-180bpm are critical intervals, which should be paid attention to.
